SPECIFIGATION forming` part of Letters Patent No. 597,441, dated January'- 18, 1898. i

Application filed August 18, 1895.4 Serial No. 559,469. (No model.)

To @ZZ whom it may concern:

Be it known that I, FRED W. SMITH, of Evanston, in the county of Cook vand State of Illinois, have invented certain new and useful Improvements in Bicycles; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the .letters of reference marked thereon, which form a part of this specification.

This invention relates to improvements in bicycles, and more especially to a construction in a bicycle by which at the .will of the rider it can be placed in such condition as to prevent it from being used or ridden, thereby preventing its being ridden awayey unauthorized persons for the purpose'of theft.

The invention consists in thematters hereinafter described, and pointed out in the appen ded claims.

One of the principal features of my invention consists in a detachable connection between the handle-bars andl the front fork, such detachableconnection being adapted to permit the release of the handle-bars from the fork, so as to leave them free to rotate independentlyof the said front fork, combined with a locking device for holding part of the connecting devices in their detached'or disconnected relation, sothat after the handlebars are released from the fork and are free to revolve no person can' secure the connection or interlocking of the handle-barswith the forks and thereby put the machine in condition for use except the owner or other person who has control of the locking device. As a separate and further improvement adapted for use in connection with the handie-bars, arranged as above described, I also propose to provide a locking or holding de'- vice by which the front forks and the steer.

ing-wheel carried thereby-may be locked or held from rotation relatively to the frame,

` thus placing the machine in condition to prevent its being steered or guided.

My improvement also includes means for adjusting the vertical position of the handlebars and other features of construction, as

will hereinafter more fully appear.

My invention may be more readily understood by reference to the accompanying drawings, in whichsame are attached. Figs. 5 and 6 are'end and side views of theclutch member which forms the, means of connecting the handle-bar part with the tubular spindle o'f the front fork. Fig. 7 is an enlarged detail section through the locking device. the key employed in connection with said locking device. Fig. 9 is anenlarged crosssectional view taken on line 9 9 of Fig. 3. Fig. 10 is a cross-section taken on line 10 l0 of Fig. 9. Fig. 11 is a detailed cross-section taken on line l1 11 of Fig. 3.

As shown in said drawings, A indicates a tubular steering-head, which is attached to the upper and lower front frame members A A2 in the usual manner.

B indicates the front fork, and B the forkspindle, which passes through the steeringhead and is provided at itsv upper and lower ends with hearing-rings b b', arranged in opposition t bearing-rings a a.'- at the upper and lower` ends of the steering-head to form the parts of the usual ball-bearings.

O indicates a tubular handle-bar post, to which are attached the handle-bars C' C. The fork-spindle B is made hollow or tubular, and the handle-barpost O is also made hollow or tubular and is inserted in the upper end of the fork-spindle in the usual manner. In this instance, however, the handlebar post,whi1e adaptedto turn o1' rotate within the fork-spindle, is not adapted for vertical movement or adjustment therein, but is permanently set at' a definite vertical position, having for this purpose connection with the spindle by means permitting relative rotary movement ot' the handle-bar post and spindle, but preventing the longitudinal -movement of said parts relatively to each other. The devices hereinshown for eecting such connection are more clearly shown in Fig. 3 and are constructed as follows:

Fig. 8 is a side view of ICO f `25 or halves, which are joined C2 is a sleevewhich is placed over the upper end of the fork-spindle in its part which projects abovetthe steeringhead, and is secured theretoconve'niently by means o'fone 5 or more screw-studs c. At its upper end the provided with an outwardlyl extending flange c'while ,its lower part is `movement,while permittingit to turn or re-k volvev freely within the fork-spindle when not (otherwise connectedwith the latter. The split sleeve C3 is hereinl sho'wn asl made in two partsy by means of bolts c4 c4,-passing through lugs e505 on opposite sides of the sleeve. Said bolts serve to clamp the parts of the sleeve around the handle-bar post and thereby hold the sleeve rigidly in 3o place on said post,

yTo now refer to the parts illustrated for effecting engagement ofi the Ahandle-bar post withA the fork-spindle when itis desired to use` the machine and for disengaging said parts 3 5 when it is desired to'leave the handle-bars free to rotate and thus put the machine in condition in 'which it cannot be used, these parts are constructed as follows:

D indicates a metal block which is inserted 4o and secured within the hollow fork-spindle below the lower end of the handle-bar post,

said block being provided in its upper surface with a transverse notch or groove d. Within the lower'end of the handle-bar post is lo- 45 cated a clutch member or thimble E, having in its lower surface radial grooves or recesses e e, Figs. 2 and 5. Between the block D and the thimble E is located a clutch member or plugF, which is' provided at its lower end 5o with a transverse projection or rib f, adapted to engage the transverse notch d of the block D, and having at its upper end two radial wings or anges f f", adapted to engage the radial recesses e e of the thimble E. The

55 plug F is permanently engaged with and held from turning by the block D; but said plug is at the same time-made vertically movable,

so that it's wings or flanges j" can be engaged with the notches of the thimble E at pleasure,

6o said plug and thimble thus constituting the two parts or members of a clutch. Said plug F is shown as madeof conical form at its upper f end and the thimble E as being made concave and of similarconical form at its lower end;

65 but this construction is not essential, and thel adjacent surfaces of the plug and thimble may be of other shape, if desired. The thimpart fotk the sleeve a jam-nut c2" therein and is pro-KA blek E is rigidlysecured within the handle bar post by brazing, soldering, or other suitrable means. The said plug F has attached 4 spindle forms a thumb or linger piece against `which pressure maybe readily applied to giveA endwise movement'tothe spindle, f Said spindle is guided' at its upper end by passing through ya guide-aperture form ed in a hollow plug orsleeve H, which is inserted `and secured in the upper end of a tube I, which tube `isin turn fitted within the'upper end of the handle-barpost. ,Thesaidspindle G is adapt-1 ed to slide vertically within the sleeve H and yisheldy at the upper limit of its movement by means of a spring J ,herein shown as made of coiled form and arranged to surround the spindle. kSaid spring is preferably arranged to. bear at its lowerend against a' ring or ange i, which is secured in the lower end of the tube I, while they upperend of the spring bears against a collar c, attached to the said t stem below the sleeve H.

The plugF is adapted for engagement with the thimble E in the lower end of the handlebar ypostlwhen the spindle is lifted to the upper limit of its movement', so that the spring ,I tends to maintain the two parts of the clutchfnamelthe thimble E and plug Fy normally in engagementwith each other; A

, downward or inward movement of the spindle against the action ofthe spring will have The upper end of said t IOO the effectof releasing the plug fromthe thimble or disconnecting the clutch, so that by pressing downward on the end of the stem l which projects above the handle-bar post the handle-bar post will be freed from the forkspindle and may be rotated at will. In the vertical movement of the plug F described the flange or proj ection f thereon slides within the notch d of the block D, such sliding of the projection in the notch affording the necessary vertical movement of the plug F for connecting and disconnecting the clutch without disconnecting said plug F from the forkspindle. l j For holding the parts of the clutch out of engagement with each other in order that the handle-bar may be free to rot-ate a locking device is provided adapted to hold the plug or movable member of the clutch from upward movement when thrust inwardly far enough to be disengaged from the sleeve E. Such locking device may be of anysuitable formas, for instance, it may be a key or a combination lock. In the constructionillustrated, however, I have shown a key-lock of the same general character as that form of lock known as a Yale lock. Said lock is shown clearly in Figs. 2, 3, and 7 and is constructed as follows:

In the upper end of the spindle G is formed a longitudinal groove K, which extends about one-half way through the stem and opens IIO iig

through the upper end of the same. Within the sleeve H is formed a longitudinal groove K', of corresponding width, which stands opposite the groove K. In the upper end of the said stem and in the same plane with the groove are formed a plurality of transverse `gue-passages lo la', arranged in' alinement wi corresponding passages 7c' in the sleeve H. Within said passages k la are located two 1o sets of sliding pins k2 7c?, of which the inner set, k2, is located in the passages of the spindle, and the outer set, kg, is arranged inthe sleeve H, the pinsin the sleeve being in alinement with those in the spindle when the latter is thrustinwardly or is at the inward limit of its movement. A series of leaf-springs h4 h4 are shown as applied to act on the outer ends of the pins k3 in such manner as to' force the latter inward. A key M is employed, which is made of fiat sheet metal and is adapted for insertion in the grooves K and K' of/the spindle and sleeve. Said key is provided with acorrugated or serrated edge fm, adapted for contact with the inner ends of the pins k2 when thekey is inserted in the groove of the spindle, into which groove the said pins are thrust by the springs 7a4 when the vparts are in their locked position, as shown in Fig. 2; The inner and outer pins k2 k3 are 3o. made of varying lengths corresponding with l the distance from a straight line of the points on the serrated edgeof the key at which the inner pins come in contact with the same, so that when the key is inserted and the pins are pushed back the contact en ds of the several inner and outer .pins will come in alinement with the joint between the spindle and sleeve and will therefore leave the spindle free to slide outwardly or inwardly under the" 4o action of the spring J or of pressure applied to the outer end of the spindle.

To render more certain and positive the outward movement of the spindle and at the same time to lessen the liability of the pins being manipulated bya tool inserted into the key-slot, the groove of the stem is provided outside of the outermost pins with a lug or projection 1c5, adapted to engage a notch vfm.' of the key. Said key is provided with a cutaway part m2 in its rear or outer edge to enable it to be inserted past said lug or projection c. The interlocking of the key with the pinor lug 71:5 obviously enables the' key to be used for drawing or pulling the spindle outward or upward. It will of course be understood. that when the spindle is thrust out-l .wardly the several outermost pins los will be lthrust or pressed against the same by the action of the spiral springs 7a4, and when the 6o spindle is thrust inwardly and reaches a point where the inner and outer pins are in alinementwith each other the outer pins will be forced into the holes by their actuatingsprings and will thus lock the stem until it is again released by the insertion of the key.

As a means of obviating the liability of the lock being .broken by force appliedfthereto -in a manner to rotate the spindle G, I construct the parts as follows: The sleeve H, instead of being rigidly secured within the tube I, is held therein and turning therein by frictional contact only, being fitted so tightly as to prevent any movement of the sleeve in' the tube under ordinary circumstances. The sleeve is held in the tube by means of a screw h, projecting through the tube and engaging a circumferential groove h', whereby the sleeve is held from endwise movement in the tube. The spindle G is held positively from rotation in such spindle by means of a lug or feather h2, which is secured in the sleeve and engages the key-groove k of the spin dle. From this construction it will be seen that if any instrument be inserted in the keygroove and then turned, with the object of breaking 0E the'locking-pins, the only result accomplished will be the rotation of the spindle and sleeve within the tube l, and such rotation may continue indefinitely without injuring any of the parts. ln order to permit such rotation of the spindle G Without aiecting the clutch mechanism, said spindle is' attached to the clutch F by having its lower end inserted and held by frictional contact in a socket f2, formed in said plug, as seenv in Fig. 2.

It will be observed that the lock, arranged as described, is adapted for automatic locking of the spindle when the latter is thrust inwardly, so that the key is required only at the time of unlocking or releasing the spindle for putting the machine in condition for use- IOO that is to say, when the machine is in working condition the handle-bar post Will be rigidly connected with the fork-spindle through the medium of the interlocking parts of the clutch, and those parts may be disconnected to free the handle-bar from the forks by merely thrusting inwardly the spindle G by pressure at its outer end, and when the stem has been thrust inwardly far enough to re.

lease the movable member of the clutch the spring-actuated pins; of the lock will engage thestem and thus hold it in its inward position. The clutch device may thus be released .and the handle-bars left free to rotate byv simply pressing inwardly on the stem G, so that the use of a key is necessary only when it is desired to release the spindle and permit the parts of the clutch to become rengaged in order to again establish rigid connection between the handle-bars and the fork. It will he'obser'ved from the above that the lock, constructed as described, is, in fact, an automatic or spriug'lock adapted to secure the locking of the parts Without the use of a key, and as far as this part of my invention is concerned the same result may be produced by any other form of spring-lock which will automatically engage the spindle or clutch-actuated part of the device.

The Stem G, sleeve H, and parts of the lock being mounted in the tube I, said tube, with all of said parts, may be made separate from the handle-bar post and inserted and secured within the same, thereby greatly simplifying the original construction of and repairs to the said parts.

To now refer to 'the locking device for the front fork, hereinbefore referred to, the same vis herein shown as arranged to be actuated of a spirally-coiled spring O, which surrounds the rod between the lower block D and a collar n on the said actuating-rod. The locking means illustrated for securing engagementv 0f the fork-spindle with the steering-head consists ofA a pivoted detent'P, which is mounted within the fork-spindle, below the block D', on a transverse pivot'p insuch manner as to swing in a vertical plane, the free end of the detent being ,adapted to be projected outwardly to slot C4 in the spindle and to engage a slot Q in the steering-head. This slot Q is shown as extending through the tube which forms the steering-head and also through a metal rein-` forcing piece or sleeve Q', inserted and `secured in the lower'part of theY tube which forms the steering-head. At the same time the slot Q is shown as arranged opposite the adjacent end of the lower tubular frame member H2, so that the detent when swung into position to engage the slot Q may pass through the steering-head without being exposed and may enter the said frame member to a greater or less extent, as may be necessary to secure a positive and certain engagement of the detent with the frame.- In a construction in which there is no room for the sleeve Q within the steering-head the detent P may engage a slot in the tube forming the steering-head and may enter the end of the frame-bar A2 in the same manner as in the case illustrated. Said detent P is provided with a horizontal part or arm p', located beneath and in position for. engagement with the lower end ofl the actuating-rod N. The downward presvsure of the said rod on said arm P ofthe detent acts to depress the same and at the same time to swing the lower or depending end of the detent laterally in engagement with the locking-slot of the steering-head. In the construction illustrated the detent is shownas being unattached to the actuating-rod, and in order to maintain the parts in engagement and to retract the dog from engagement with the steering-head a suitable spring is applied to the detent, said spring, as herein shown, consisting of a leaf-spring R, secured to the spindle and acting through the slot thereof against the outer edge of the detent.

From the construction describedit will be obvious that when the stem Gis thrust inwardly the actuatingrod N will also be thrust inwardly and thereby project the detent P outwardly into the locking-slot of' the head, and thus lock the fork from turning at the same time when the fork-spindle is free from connection with the handle-bars; and the latter are left free to turn independently of the fork. Moreover, the detent will remain in engagement with'the Asteering-head and will be held from turning until by the use of the key the spindle shallhave been unlocked and the parts of the clutch again engaged to hold the handle from turning relatively to the forkspindle.v It is to be noted in this connection, however, that the plug F merely forms a means of transmitting motion from the spindle G' to the actuating-rod N, and that said actuating-rod and the locking device operated b it. would operate in the same manner, as above described, if the clutch device for aording detachable connection of the handle-bars with the forkspindle were entirely absent. A machine .may therefore be made embodying this part of my invention in which the locking of the front fork only is Vrelied upon as a means of safety or to `prevent the Wheel from being used.

The handle-bar posti-in the construction.

.described has no vertical adjustment for raising and lowering the position `of the handles. I have, therefore, provided a means by which the Vfree end of the handle-bars may be lifted or depressed to bring the handles at aheight suitable for the rider. To this end I provide a rotary connection between each handle-bar and the upper end of the handle-bar post in connection with fastening or locking devices by which the handle-bars may be rigidly secured in any position in which they may be placed. The special form of attaching device illustrated is made as follows:' Each handlebar O is made separate from the handle-bar post, and on the opposite sides of the latter, at its upper end, are formedt'ubular sockets O5, the outer ends of which are screw-threaded and ,split longitudinally. -Saidsockets are adapted to receive the smooth inner ends of the handle-bars and are provided with exterior screw-threads adapted for engagement with thimbles C6 C6, whichare tapered interiorlydn suchmanner that when screwed upon the split ends of the sockets they will clamp the parts of thevsame rigidly against the handle bars. While these means for clamping or holding the handle-bars at a desired angle are practicaland convenient, yet I do not wish to be limited to this exact construction, as other clamping or holding means may be employed for securing the same result.

The construction described, embracing a locking device for holding the front fork from turning and also the device for releasing the handle-bars and leaving them free 'to rotate, is not only a great advantage as' affording IIC ` means for preventing unauthorized use of .handling iss the bicycle, but is of great convenience in lhandling the machine or storing it when not in use or when it is being shipped by train or otherwise. When the front fork is locked from rotation, the bicycle may obviously be allowed to rest against an upright object withI much less liability of falling than when the' -front fork i's left free t'o turn.

Moreover, the Wheel may be readily placed against a vertical surface or Wall, because not only will the front wheel remain in the same plane with the rear wheel, but the handle-bars may be turned soas to bring them inthe same plane with the machine-frame and away from the wall, if necessary, so that the machine will not only stand securely, but will occupy but very little space. Similarly, in 4transporting the bicycles by railway-as, for instance, when they are checked as baggage-they can be much more easily handled by the baggagemen and others if the front wheel be rigid and the handles befree to turn into a position in the same plane with the frame. Itis not uncommon when a number of .bicycles are being carried in a baggage-'car for the baggageman to throw or pile a number of them one on top of the other, and as ordinarily constructed they occupy much room and are very liable to be damaged in such When the front wheel is rigidly secured and the handle-bars are free to turn, they may be packed more closely by placing the handle-bars in position at right angles to the usual position, while the locking of the front fork prevents the same from oscillating or vibrating when the machine is lifted or moved about, so that when arranged as described the front wheel and handle-bars are less likely to be brought forcibly in contact with other objects, and the machine is therefore less liable to breakage or injury. Similarly, in the handling of bicycles by baggagemen they are, as ordinarily constructed, likely to be injured by carelessly placing or standing them against other objects, the tu rning of the frontwheel allowing them to easily fall, whereas if the front wheel be locked as described they will remain where placed if rested against any object either temporarily or when deposited in a car or place of storage.
